Thornton, Robert John

HCR DIARY 11.5.1826 calls on Blake, Thornton
Presumably Robert John Thornton (DNB 1768-1837). Robinson had met William Blake (DNB 1757-1827) with John Linnell (DNB 1792-1882) at the Aders. Thornton was Linnell's doctor and had met Blake through Linnell in 1818, commissioning him to make woodcuts for his edition of Virgil. Thornton nearly dismissed Blake's work but was persuaded otherwise by dining at the Aders when Thomas Lawrence (DNB 1769-1830) and James Ward (DNB 1769-1859) both expressed admiration for Blake's work.
